Common wireless communication services recognition for GSM, UMTS and LTE via synchronization channels detection

Abstract

This paper discusses about design of common wireless communication services recognition for three different standards, i.e. Global System for Mobile Communications (GSM), Universal Mobile Telecommunications System (UMTS) or Wide-band Code division Access (WCDMA), and Long Term Evolution (LTE), also known well as 2G, 3G, and 3.9G respectively. To recognize them using a common system, we propose performing within synchronization channel detection since the similarity in cell search procedures i.e. always detect synchronization signals. To minimize resources, we prefer using autocorrelation to detect GSM and LTE synchronization signals and match filter for UMTS synchronization signal. However, it is not enough to distinguish each others. Therefore, we also propose to recognize the peak period of the autocorrelation output as a main concept to distinguish the standards. We design this system using symplify DSP tool and simulate in simulink. The simulations are performed within AWGN channel and show good performance even with 10 dB SNR. Moreover, FPGA implementation for target device Virtex 4 XC4VLX200, the proposed design can be implemented within 24171 look up tables (LUTs).
